A system includes a luminaire having a head configured for rotation relative to a fixed enclosure of the luminaire. The head includes a camera access port. The system also includes a camera module configured to be removably mounted to the camera access port of the luminaire, and a cover plate configured to be removably mounted to the luminaire head to cover the camera access port. A weight of the cover plate approximately matches a weight of the camera module.

Systems for a luminaire

A luminaire is provided, having an enclosure and a chamber air coupled to the enclosure. The enclosure includes luminaire components that emit a light beam, has an opening, and is otherwise sealed. The chamber includes a drying agent, two openings, and is otherwise sealed from the external air. One opening of the chamber is coupled by a sealed air coupling to the opening of the enclosure. The other opening of the chamber is completely covered by a membrane that allows air to pass through the material while reducing the passage of water droplets in the air. The enclosure may include sensors that measure air pressure, air humidity, and/or air temperature of the enclosure. The luminaire may include a control system configured to collect data from the sensors and to send information related to the collected data to a user of the luminaire via a communication channel.

System and method for controlling the humidity and pressure in a luminaire

A luminaire includes a light source and a framing shutter system. The light source is configured to emit a light beam. The framing shutter system includes an aperture that is configured to receive the light beam. The framing shutter system further includes a plurality of shutter blades configured to be positioned across the aperture and mask a portion of the light beam. Each of the shutter blades includes a blade substrate material having a front surface that is configured to receive the light beam and a rear surface on an opposite side of the blade substrate material from the front surface. The front surface of each shutter blade includes a first coating that is configured to reflect one or both of light and heat. The rear surface of each shutter blade may include a second coating configured to reduce reflection of light from the rear surface.

Coating for a framing shutter for a luminaire

A luminaire includes a light source configured to generate an emitted light beam, and a beam reducer configured to move between a first position and a second position. In the first position, the beam reducer is outside the emitted light beam, and in the second position, the beam reducer receives the emitted light beam and occludes an outer portion of the emitted light beam to emit a reduced light beam having a smaller beam angle than the emitted light beam. The luminaire also includes a beam size iris configured to receive (i) the emitted light beam when the beam reducer is in the first position and (ii) the reduced light beam when the beam reducer is in the second position. The beam reducer is configured to move to the second position in response to an aperture of the beam size iris being smaller than a predetermined threshold value.

A luminaire including an LED light source, a plurality of color filters, an optical device, and a control system is provided. In response to receiving an optical device setting value via a data link, the control system moves the optical device according to the setting value, calculates modified positions for one or more of the color filters based on an effect of the optical device on the color of the light beam of the luminaire, and causes the one or more color filters to move to their modified color filter positions, in order to reduce the effect of the optical device on a beam color emitted by the luminaire.

Luminaire optical device color compensation

A luminaire and optical system are provided. The luminaire includes a head and power circuits configured to provide electrical power to electrical circuits of the head. The head includes an optical system with a light source support plate, a support structure movably coupled to the light source support plate, and a lens support assembly removably coupled to the support structure. The light source support plate includes LED light sources, each configured to emit a light beam. The support structure includes a plurality of apertures, configured to pass the light beam from the LED light sources without modifying the light beam. The lens support assembly includes lenses, each aligned with an optical axis of one of the LED light sources when the lens support assembly is coupled to the support structure. The lens support assembly is removable from the head without removing the support structure from the head.

Removable lens system for a luminaire

A luminaire includes an enclosure, an air valve, and a chamber. The enclosure includes a sealed cover and light beam emitting components. The air valve is air coupled between the enclosure and the chamber. The chamber includes a drying agent and has an opening with a membrane completely covering the opening. The membrane passes air while reducing the passage of water droplets in the air. The air valve blocks air passage between the enclosure and the chamber when closed. A method for testing to determine adequate sealing of an enclosure of a luminaire includes closing an air valve to seal the enclosure from outside air, activating a heat-generating component, determining whether an air pressure in the enclosure increases by more than a threshold value, and sending a signal indicating a result of the determination. The method includes deactivating the heat-generating component and opening the air valve.

A luminaire includes a luminaire mechanism, a stepper motor, an absolute multi-turn rotational position sensing system, and a control system. The stepper motor moves the luminaire mechanism. The absolute multi-turn rotational position sensing system includes absolute rotational sensors that detect absolute positions of a cam indexer on the motor shaft and an indexer wheel coupled to the cam indexer. The indexer wheel rotates by a predetermined amount in response to one full rotation of the cam indexer. The control system determines an absolute position of the luminaire mechanism based on information from the absolute rotational sensors relating to the positions of the cam indexer and the indexer wheel. The control system receives a commanded position for the luminaire mechanism and causes the stepper motor to move the luminaire mechanism to the commanded position based on the absolute position of the luminaire mechanism.

Absolute position sensing system for stepper motor mechanism

A luminaire is provided that includes a head, a movement system, and a control system. The movement system rotates the luminaire head around an axis of rotation. The movement system includes a motor and a braking system. The motor moves a luminaire mechanism. The luminaire mechanism may be a gobo wheel, a lens, or other optical device of the luminaire, or it may be the luminaire head or the luminaire yoke. The control system determines whether the motor is rotating and engages the braking system when the motor is not rotating. When the motor is stopped, the control system may store in non-volatile memory a current absolute position of the luminaire mechanism.

Braking system for an automated luminaire

A luminaire is provided, having first and second enclosures, a pipe, and a chamber. The first enclosure includes luminaire components that emit a light beam, has two openings, and is otherwise sealed. The second enclosure includes electronic circuits coupled to the luminaire components, has an opening, and is otherwise sealed. The first enclosure rotates relative to the second enclosure. The pipe couples an opening of the first enclosure to an opening of the second enclosure, rotates relative to the first enclosure, and is otherwise sealed. The chamber includes a drying agent, two openings, and is otherwise sealed from the external air. One opening of the chamber is rotatably coupled to an opening of the first enclosure. The other opening of the chamber is completely covered by a membrane that allows air to pass through the material while reducing the passage of water droplets in the air.

A luminaire includes a white light LED light source emitting a light beam that that is filtered by first and second color filters. An optical device modifies the filtered light beam. A control system receives a commanded value for the optical device and responds by causing the optical device to move based on the commanded value; determining a Duv change in the light beam caused by the optical device; determining positions for the color filters based on the Duv change, a current correlated color temperature (CCT) isotherm value, and a current Duv value; and moving the color filters to their determined positions. The control system may alternatively receive a command with a Duv value and respond by determining color filters positions based on the received Duv value and a current CCT isotherm value; and moving the color filters to their determined positions.

Duv control of luminaire beam color

An automated luminaire includes an array of light sources and a beam shaper. The array of light sources produces a first light beam. The beam shaper receives the first light beam and produces a second light beam. The beam shaper includes an array of convex lenslets and an array of concave lenslets. The convex and concave lenslets have non-circular shapes when viewed along an optical axis of the first light beam. The convex lenslets nest into the concave lenslets. The convex and concave lenslets rotate about an axis of rotation that is parallel to the optical axis and is located in the first light beam.

Beam shaper

A method is provided for removing a light-emitting diode (LED) module from a luminaire that has a controller and a housing. The housing encloses an optical system that includes the LED module and other optical devices. The method includes electrically uncoupling an LED circuit board of the LED module from the controller. The method further includes mechanically uncoupling the LED module from the luminaire without removing other optical devices of the optical system from the housing.

The luminaire includes a controller and an optical system with adjustable optical elements and an LED module with an LED circuit board electrically coupled to the controller. The LED circuit board includes an array of LEDs configured in two or more concentric zones, each zone including a plurality of LEDs. Intensity of the LEDs of a first zone is controlled independently of the LEDs of a second zone. The controller controls the intensity of at least the first zone based upon a configuration of the adjustable optical elements. The LED module can be removed from the luminaire without removing other elements of the optical system by electrically uncoupling the LED circuit board from the controller and mechanically uncoupling the LED module from the luminaire.
